Take the bottom part of the debug, not the whole thing.

^Is that the most bottom part of your debug?

You have too many tags in inappropriate folders, like having a tags folder inside a tags folder and so forth. Delete some tags and then try again.

Ok, first of all, debug.txt will never cause problems. I tells you what the source of your problem is. Every time an HEK application encounters an error, it will create a new paragraph in the debug.txt file telling you what the error is. So if you try to open sapien and it crashes, a new entry will be created at the bottom of the file.
